If they can get the first off the line 737 800's out of LBA on a 5 hour sector on a summers day... You bet they can get a new A330 200 out. I don't even think a -300 would break a sweat.
Whether there would be issues in getting an A332 to Orlando or Cancun... I don't know to be honest. MON managed for years with older gen A332's out of NCL which is only a couple of hundred feet longer, yet significantly flatter
